The problem of the age of the observable universe - the time back to the "big bang" - has puzzled laymen, churchmen and scientists for many years. In this paper the bias concerning cosmochronology lies in a prejudice for results obtained through nuclear chronometers. Radioactive elements serve as nuclear chronometers or aeon-glasses and make it possible to determine how long ago production of the elements began in our Galaxy, the Milky Way. More conventional determinations of the age of the universe and the Hubble time are discussed as well as the possible need for dark, non-baryonic matter to bring the total to the critical value required by the inflationary model with zero curvature parameter and zero cosmological constant. Other studies which support Ω0 ≈ 1 and even Ω0 (baryon) ≈ 1 are briefly discussed.
